Eastern Harbour Crossing

Eastern Harbour Crossing. The Eastern Harbour Crossing is a dual-tube immersed road tunnel in Hong Kong, forming a critical link beneath Victoria Harbour between Kwun Tong District on the Kowloon peninsula and the Eastern District on Hong Kong Island. Opened in 1989, it was the second fixed vehicular crossing of the harbour after the Cross-Harbour Tunnel and was built to alleviate chronic traffic congestion. The tunnel carries Route 2 and is a major conduit for traffic between eastern Kowloon and the North Point and Quarry Bay areas, playing a vital role in the territory's transport infrastructure.

History

The need for a second harbour crossing became pressing in the 1970s as Hong Kong's economy boomed, leading to severe congestion at the sole Cross-Harbour Tunnel. The Hong Kong Government initiated planning, and the project was ultimately developed under a Build-Operate-Transfer model, a pioneering approach for the territory's infrastructure. A consortium led by Kumagai Gumi and including China International Trust and Investment Corporation (CITIC) was awarded the franchise. Construction commenced in 1986, and the tunnel was officially opened on 21 September 1989 by then-Governor Sir David Wilson. Its opening immediately redistributed harbour traffic and spurred further development in eastern Kowloon and along the Island Eastern Corridor.

Design and construction

The Eastern Harbour Crossing is a long immersed tube tunnel, consisting of two separate steel tubes, each carrying two lanes of traffic. The tunnel sections were fabricated in Nagasaki by Mitsubishi Heavy Industries and towed to Hong Kong for installation on a dredged trench on the harbour bed. The engineering work involved significant coordination with the Hong Kong Observatory due to typhoon risks during the tow. The land-based approaches on the Kowloon side connect to the Kwun Tong Bypass and Cha Kwo Ling Road, while the Hong Kong Island portal integrates with the Island Eastern Corridor. Ventilation buildings are located at both ends, with the distinctive red and white chimneys at Quarry Bay becoming a local landmark.

Operations

The tunnel is operated by the New Hong Kong Tunnel Company Limited under a franchise that originally lasted 30 years. Day-to-day operations encompass traffic management, toll collection, and maintenance of the tunnel's extensive safety systems, including ventilation, lighting, fire protection, and CCTV surveillance. The control centre monitors traffic flow and coordinates responses with the Hong Kong Police Force and Hong Kong Fire Services Department for any incidents. The tunnel has consistently handled a high volume of daily vehicles, though its traffic share has been affected by the later openings of the Western Harbour Crossing and Tsing Ma Bridge.

Tolls and traffic

Tolls for the Eastern Harbour Crossing have been a subject of public and legislative debate, as the franchise agreement allowed the operator to adjust fees. Historically, its tolls were often higher than those of the Cross-Harbour Tunnel, influencing driver choice and contributing to congestion differentials between the three harbour crossings. The toll structure varies for different vehicle classes including private cars, taxis, and goods vehicles. Traffic figures are monitored by the Transport Department, and the crossing remains a key alternative route, especially during incidents or maintenance closures at the other tunnels. Discussions on toll harmonization have frequently involved the Legislative Council.

Future developments

The original operating franchise expired in August 2016, triggering a series of negotiations. The Government of Hong Kong subsequently decided to take back the tunnel under the Build-Operate-Transfer terms. The government assumed full ownership and operational control on 7 August 2016, with tolls immediately reduced. The long-term future of the crossing is now integrated into the government's broader transport strategy, which includes managing cross-harbour traffic distribution among all three tunnels and potential new infrastructure like the proposed Tseung Kwan O – Lam Tin Tunnel. Its operation is now managed by the Transport Department, aligning its role with public policy objectives for Hong Kong's Victoria Harbour crossings.
